软盘更换(DISKETTE CHANGE)信号电路启用于1.2MB软盘驱动器,用以监测软盘更换与否——换盘防错功能。MS DOS V3.20及以上版本DOS使用手册对应为DRIVER.SYS、DRIVPAM所涉及的CHANGE LINE功能。 实践表明,凡用户在不该更换软盘时(如原盘文件处于
The DISKETTE CHANGE signal circuit is enabled on the 1.2MB floppy disk drive to monitor the floppy disk replacement or not - the disk changer’s error-proofing feature. MS DOS V3.20 and above DOS user manual corresponds to DRIVER.SYS, DRIVPAM involved CHANGE LINE function. Practice shows that where the user should not replace the floppy disk (such as the original disk file
